COOLING COIL FOR REFRIGERATORS Filed April l1, 1950 gli- @atented o @s 1332 .UNITED STATES PATENT oFFlcE WD'JLIAM SLOAN, 0F EGLEV-JILE, PENNSYLVANIA GOOIJNG COIL BEFBIGEBATORS .application ma apra 11,

The object of the invention is to provide improvement in cooling coils and especially in means for adapting such coils to the ordinary household refrigerator. y

e Another object is to provide a coil of tubingl in combination with means forA maintaining the convolutions of such coil inl'a plane, so that the coilias a unit will fit closely against an inner wall surface of a refri rator.

A further object is to provi e a system whereby such coil may be operatively mounted and.; connected with one or more extraneous sources of water supply andwith a discharge valve also upon the outside of a refr' erator. n A Y till another object is to provide an improved receptacle, operative to receive the neck of and support in inverted position a bottle of liquid, adapted to discharge its contents through said receptacle into saidcoil,

and to rovide means foroperatively securing su receptacle to the top refrigerator wall.

With these and other objects in mind, the present invention comprises further details of construction and operation which will be fully brought out in the following description when read in conjunction with the accompanying drawings, in which Fig. 1 is a pers ctive view of a cabinet representing a refrigerator and one em odimenijl of the invention operativelyinounted in association therewith Fig.' 2 is an enlarged fragmentary vertical section throu h the supporting receptacle for an inverted ttle of water or other liquid; Fig. 3 is an enlarged' fragmentary vertical sectionoffthecooling and left-hand wall.A ofthe cabinet as v1ewed"'joint.

Serial No. 443,497.

mally closed by means of a suitably mounted door 7 a bottom wall 8 closing the lower portion of the interior of such refrigerator. Each of these walls and door it is to be understood are of any suitable cross sectional structure, but ingeneral comprise relatively outer and inner spaced wall casin 9 and 10, separated by any suitable form of heat insulating material 11. Y v A Through the top wall 1 is drilled a bore 12, 60 through which is passed one end 13 of a. tube, the lower end 14 of which is deflected angu- 15. Upon the outer surface of said top W is secured' a plate 16 by any suitable means 17, to said 65 plate in turn beingY welded or otherwise unitarily secured the bottom 18 of a. receptacle,

Vwhich also comprises upwardly extending flared or bell-shaped walls 19, the outer periphery 20 of which is provided with a con- 1 t'inuous groovej21 in which is sitioned a gasket 22, against which rests t e neck portion 23 of a bottle 24 containing water or other liquid, the terminal portion 25 of the bottle neck 23 fitting loosely within the lower 75 portion of said receptacle, while the continuity of the gasket 22 is broken at one or more points 26, to provide air vents for the admission -of air to the interior of the bottle 24 as the contents of the same liow therefrom. The so plate 16 and bottom 18 of said bottle rec?- tacle are provided with alignedapertures through which extends the upper p ortion 13 of said tube, and which upper portlon above the inner surface of said receptacle bottom S5 wall is flared and soldered or welded at 2 8 to said receptacle wall to make a hquid-tlght Formed inside of the refrigerator is a coil 29j of ofany desired number of con 90 voliitionswbichgpreferably 11e in a single plane, and-fare .secured therein andin equal spaced relation-with respect to one another f ,'.by vrneansof oppositelypositioned 'bars 30,

secured together asshown in Fig. 5Y by anyo suitable means 31. The inner end 32 of sa1d coil is connected through an L 33 and nlpple 34 to a T 35, whence a nipple 36 connects sa1d T to a valve 37, in turn connected through the medium of a tube A38 with the coupling 15. 100

That end of the T opposite to the nipple 34 is`connected by way of another nipple 39 to a valve 40 and thence through a nipple 41 to a coupling 42, the opposite side of which is connected to the inner end 43 of a pipe which extends through the rear wall 4 offthe refrigerator and is connected thereto by any suitable air sealing medium, such as rubber, said pipe upon the oute'r side andy to the rear of the refrigerator passing along the path indicated by the dotted lines 44 and-being provided with a coupling 45, by means of which this pipe is adapted to be connected to a continuous fresh water supply from any desired source.

The opposite end 46 of the coil 29 is provided with an L 47 which is connected through, the medium ofa nipple 48 'with any suitable type of faucet 49 uponlth'e outside of the refrigerator, said nipple 48 passing through theadjacent wall' of the latter and an airtight connection therewith being insured'by means of the gaskets 50. For convenience, the outer surface of the faucet-supporting Wall` may be provided with a suitable bracket 51, upon which m rest a drinking receptacle or glass 52.. ithinl the refrigerator the side Walls are provided with any suitable form of brackets 53, which. removably suplao port shelves 54 of any suitable construction and number.

In the operation of this device, it will be noted primarily that the coil 29 comprises a unit which may be inserted into and removed from within a refrigerator at all/times as a unit, and the weight of' which in operation is preferably supported directly bythe bottom wall 8. After connecting the ends 32 and 46 of the coil to the various couplings as hereinbefore described, and after inverting a bottle of Water or other'liquid as shown in Figs. land 2, so that its contents may ilow freel into the receptacle 19, the contents of shaped receptacle adapted to receive the neck of and support abottle in inverted ositlon,

`an annular gasket carried by and ad]acent to the free edge portion of said receptacle to cushion a bottle with respect thereto, a tube extending from within said receptacle through saidbore and into said cabinet, a planar coil "of concentric convolutions of tubingsupported upon one end parallel with and adjacent to the inner surface of a side wall of said cabinet,tubular means connecting one end of said coil to said tube, a dischar evalve connected to the opposite end of said coil, a valve in said tubular means, a second tubular means connecting said lirst end of said coil to a second source of liquid, and a valve in said second tubular means, said valves in said tubular means being adjustable to operatively connect said coil either to said receptacle or to said second source.

In testimony whereof I have affixed my signature.

this ottleimay be permitted to pass through the cooling coil and taken therefrom upon and by means of actuations of the faucet 49, after opening the valve 37 and closing the valve 40. On the other hand, if water from a constant source is desired through the pipe indicated at 44, the valve 37 is closed and the valve 40 opened, whereupon this water may flow through said coil and be drawn therefrom through said faucet as desired. 4

However, while various pipe connections have been hereinfdescribed in detail, various alterations` therein and in details, of oonstruction of the coil and its associated'ilements may be made without departing from the scope of the invention as defined by the appended claims.

Having thus described my invention, what I claim 'and desire to protect by Letters Patent of the 1United States is The combination of a cabinet having a top wall provided with a bore, an inverted bell-
